Travel and Expense

Travel and expense refers to the operational costs employees incur when travelling for work or carrying out business activities away from their regular work base. Commonly known in finance as T&E, this spending category encompasses transport, lodging, meals, client meetings, and minor incidental costs. For finance teams, managing travel and expenses effectively is critical to maintaining cash control, preventing budget leakage, and ensuring compliance with HM Revenue and Customs (HMRC) regulations.

What is travel and expense (T&E)?

Travel and expense (T&E) represents the combined costs of work-related travel and associated daily spending. In corporate accounting, T&E is classified as an operating expense and forms a controllable part of an organisation's operating budget.

Because business travel expenses involve numerous individual transactions across distributed teams, they carry substantial administrative overhead. According to a GBTA Foundation and HRS study, the average cost to process a single business expense report manually is $58, taking roughly 20 minutes of employee and administrative time. Correcting an erroneous expense report costs an additional $52 according to the GBTA Foundation, bringing the total processing and correction cost to $110.

Beyond processing costs, T&E spending can be vulnerable to compliance oversights and policy misuse without adequate internal controls. Establishing clear oversight and automated approval workflows helps finance teams catch discrepancies early and maintain budget discipline.

What does travel and expense include?

T&E spending covers several distinct categories, each with its own tax and accounting considerations.

Transportation and accommodation

Transportation covers airfare, rail tickets, vehicle hire, and fuel incurred during business travel. When staff use personal vehicles for work, employers often reimburse them through an approved mileage allowance. Accommodation includes hotels, serviced apartments, and short-term rentals required for overnight business trips.

Subsistence and meal allowances

Travel and subsistence covers meals and refreshments purchased while an employee is travelling on company business. Employers can reimburse actual receipted meal costs or provide flat-rate allowances using a per diem structure. In the UK, HMRC sets benchmark day subsistence rates: £5 for qualifying travel lasting more than 5 hours, £10 for travel over 10 hours, and £25 for travel lasting over 15 hours and extending past 8:00 pm. When employers pay benchmark scale rates without collecting individual meal receipts, HMRC rules prohibit reclaiming input VAT on that spending.

Incidental business expenses

Incidental costs are minor expenses that arise while staying away from home on business, such as Wi-Fi charges, parking fees, highway tolls, or emergency laundry during extended stays. Because tax treatment depends on specific statutory conditions, finance teams should consult official HMRC guidance on incidental overnight expenses to confirm current thresholds and reporting rules.

HMRC rules and tax relief for travel expenses

Understanding key HMRC provisions protects businesses from surprise tax assessments and ensures employees receive legitimate reimbursements without unintended tax liabilities.

• Ordinary commuting vs business travel: Travel between an employee's home and their permanent workplace is classed as ordinary commuting under Section 338 of the Income Tax (Earnings and Pensions) Act 2003 (ITEPA 2003). Employers must distinguish regular daily travel from qualifying journeys to temporary workplaces.
• The 24-month temporary workplace rule: Travel to a temporary workplace qualifies for tax relief. Under Section 339 of ITEPA 2003 and HMRC guidance (EIM32080), a workplace ceases to be temporary the moment an employee spends, or is likely to spend, 40% or more of their working time at that workplace over a period that lasts, or is likely to last, more than 24 months.
• Approved Mileage Allowance Payments (AMAP): For employees using personal cars or vans for business travel, employers can reimburse up to 55p per mile for the first 10,000 miles in a tax year (increased from 45p from 6 April 2026), and 25p per mile thereafter, completely free of tax and National Insurance. Company-provided cars are ineligible for AMAP; employers should consult HMRC guidance on Advisory Fuel Rates for business travel in company vehicles.
• Client entertainment restrictions: Hosting prospective or existing clients is often recorded inside T&E budgets, but it does not qualify for tax deductions. Section 1298 of the Corporation Tax Act 2009 explicitly disallows client entertainment costs from reducing corporate taxable profits.

Core components of a travel and expense policy

A well-structured travel policy and companion expense policy provide unambiguous guidelines for travelling employees while protecting corporate funds. Effective policies include several core elements:

• Eligible spending limits: Define reasonable spending caps for accommodation, daily subsistence, and ground transport by city or tier.
• Booking procedures: Specify whether staff must book via designated travel portals or corporate accounts to secure negotiated rates.
• Payment methods: Outline whether staff should pay with corporate cards or submit an expense claim for out of pocket expenses.
• Receipt requirements: Mandate itemised VAT receipts for all transactions above a set threshold, ensuring prompt VAT recovery.
• Approval workflows: Establish clear spending thresholds where department heads or finance directors must pre-approve bookings.
• Duty of care standards: Set guidelines that support employee safety during travel, including driver licence checks and vehicle roadworthiness verification for personal vehicles used for business journeys.

Best practices for travel and expense management

Modernising your travel and expense management workflow replaces paper receipts and spreadsheets with seamless control.

1. Equip teams with corporate cards: Distributing smart corporate cards with pre-set spending limits eliminates out-of-pocket employee burden and prevents unapproved expenses before they happen.
2. Capture receipts instantly: Mobile apps with optical character recognition let travellers snap receipts at the point of sale, matching transactions automatically and eliminating lost receipts.
3. Automate policy enforcement: Configure software to flag weekend purchases, duplicate invoices, or expenses exceeding per-meal allowances in real time.
4. Sync directly with your accounting software: Integrate expense data directly into your general ledger to accelerate month-end close and provide accurate cash flow visibility.
5. Audit regular spending patterns: Review departmental T&E patterns periodically to identify preferred vendor discount opportunities and spot anomalous claims early.
